The weaponeers became quite worried when three satellites in low earth orbit were disabled. These man-made radiation belts eventually crippled one-third of all satellites in low earth orbit. Seven satellites failed over the months following the test as radiation damaged their solar arrays or electronics, including the first commercial relay communication satellite, Telstar. Detectors on Telstar, TRAAC, Injun, and Ariel 1 were used to measure distribution of the radiation produced by the tests.
I know a former mate spent the '70's working for RACAL on hardening mlitary comms, but are there any proper engineers on here with relevant knowledge prepared to predict the effect on ? equipment like PC's in earthed metal cases? Hand-held kit like smartphones? Internet infrastructure?
Surely it's worth upping the specs of public infrastructure to protect them from an effect which, as been pointed out could equally well be caused by a natural solar event as naughtiness by a rogue state.From Great Britain to Little Britain in one generation! Ozymandias was right.

The committee chairman does not appear to have a financial interest in any hardware manufacturers, although he does have a prior financial interest in insurance brokers so there is arguably an angle for him here.
Quite a strong Israeli connection though... make of that what you will.
Iran are a long way from having ICBM that can be detonated in space. Realistically the only threat in this regard is the Russians.
The blast radius for thermonuclear weapons detonated at altitude (but not in space) is much larger and as has been pointed out the EMP radius too. The "downside" from a military point of view is that there is no nuclear winter and much of the harmful radiation dissipates into the atmosphere."If a terrorist organisation wanted to knock out the moral compass of Britain, all they'd have to do is to kill 100 celebrities at random. The entire country would have an instant nervous breakdown."

If anyone is really interested (or has a lot of time on their hands) in reading a proper assessment of effects of EMP on national infrastructures, read the report in the link below:
Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack - Critical National Infrastructures
Warning: It's a 7MB PDF report and is about 200 pages long.
p.s: Might be useful if your MPs used this as a starting point, not engage another consultancy using lots of taxpayers' £££ to do produce a "pre-liminary analysis", which would be pretty much exactly the same. Just a suggestion.

However, should the fireball touch the ground wholly or partially then whatever material that gets inside the fireball gets heavily irradiated. And that will result in a lot more fallout - ridiculous quantities more, if you read up on some of the old ground tests.
Modern weapons are designed to use the minimum mass of fissile material per bang, so fallout for air bursts will be even lower than for 1940s technology bombs. And if you want to kipper a city, the best bet is to use several smaller weapons as airbursts to spread the damage wide and set it on fire to let the firestorm do the real damage. It's the burning cities that drive nuclear winter, not the nukes themselves.
And here airburst isn't very high as these things go, I think the blasts during WW2 were both under 1000m in altitude. Starfish Prime was 400km high, by way of comparison.
The real worry during the Cold War as far as radioactive contamination went was the use of big ground bursts to destroy hardened ICBM silos and other hard targets. Then you would get some really ugly fallout plumes.Feles mala! Cur cista non uteris? Stramentum novum in ea posui.

I explode my nuclear space bombs over the missus's atmosphere as often as possible, alas, never done any lasting damage to the slag.
